Although carbon dots (CDs) have been widely investigated as the fluorescence material, research on room temperature phosphorescence (RTP) CDs is still limited. In this work, diethylenetriaminepentaacetic acid (DTPA) was employed raw material to synthesize quantum (denoted CQDs-1) by a hydrothermal method. The resulting CQDs-1 inherited C═O groups and N atoms from DTPA, which promoted formation of triplet excitons under light excitation. On basis, were dispersed in poly(vinyl alcohol) (PVA) matrix prepare CQDs-1-PVA composites that exhibited an optimal emission peak at ∼466 nm emitted visible afterglow lasting for 8 s. Moreover, tartaric (TA) combined with DTPA CQDs-2, induced π–π conjugated areas CQDs. As result, wavelength slightly red-shifted, duration time CQDs-2-PVA composite increased 9 Due ultralong-lifetime RTP properties CQDs-based composites, their applications fields information encryption anticounterfeiting also investigated. Overall, our work offered convenient avenue synthesis high-quality
